Abstract
Background:
Compound containing sulfonamide, pyrazole and chalcone groups are
important in medicinal chemistry. They have a wide range of biological activities, including carbonic
anhydrase (CA) inhibitory activities.
Introduction:
Carbonic anhydrase I and II inhibitors are used for the treatment of diseases, such as
retinal and cerebral edema (CA I), epilepsy, and glaucoma (CA II). However, the currently available
drugs have some limitations or side effects. Thus, there is a need for new drug candidates to
overcome these issues. In this study, a series of compounds, (E)-4-(4-(3-aryl)-3-oxoprop-1-en-1-yl)-
3-phenyl-1H-pyrazol-1-yl) benzenesulfonamides MS4-MS10, were designed to discover new CA
inhibitors using a hybrid approach.
Methods:
Compounds MS4-MS10 were synthesized as shown in Scheme 1, and their chemical
structures were confirmed by 1H NMR, 13C NMR, and HRMS spectra. The CAs (E.C.4.2.1.1) inhibitory
effects of MS4-MS10 were tested on the hCA I and II isoenzymes using previously reported
procedures.
Results:
The CA inhibitors MS4–MS10 gave IC50 values (nM) of 27.8–87.3 towards hCA I and
24.4–54.8 towards hCA II while the IC50 values for reference drug acetazolamide were 384.2 (hCA I)
and 36.9 (hCA II). MS7 and MS9 exhibited 13.8 (hCA I) and 1.5 (hCA II) times more potent CA
inhibition than the reference compound acetazolamide, respectively.
Conclusion:
MS7 (Ar: 2,4,5-trimethoxy phenyl) and MS9 (Ar: 3,4-dimethoxy phenyl) were the
most promising compounds of our series with the lowest IC50 values towards hCA I and hCA II,
respectively, and can be considered for further studies.

Abstract
New imidazolinone-based benzenesulfonamides 3a-e and 4a-e were synthesized in three steps and their chemical structures were confirmed by 1 H NMR (nuclear magnetic resonance), 13 C NMR, and high-resolution mass spectrometry. The benzenesulfonamides used were sulfacetamide (3a, 4a), sulfaguanidine (3b, 4b), sulfanilamide (3c, 4c), sulfadiazine (3d, 4d), sulfamerazine (3e), and sulfathiazole (4e). The compounds were evaluated against carbonic anhydrase (CA) and acetylcholinesterase (AChE) enzymes to obtain possible drug candidate/s. The lead compounds of the series were 3a and 4a against human CA (hCA) I, whereas 3d and 4a were leads against hCA II in terms of Ki values. Series 4 includes more effective CAs inhibitors than series 3 (except 3d). Series 4 compounds having a nitro group (except 4d) were 3.3-4.8 times more selective inhibitors than their corresponding analogues 3a-d in series 3, in which hydrogen was located in place of the nitro group, by considering Ki values against hCA II. Compounds 3c and 4c, where the sulfanilamide moiety is available, were the leads in terms of AChE inhibition with the lowest Ki values. The use of secondary sulfonamides was a more effective modification on CA inhibition, whereas the primary sulfonamide was the effective substitution in terms of AChE inhibitory potency.

Abstract
The novel compounds with the chemical structure of N-({4-[N'-(substituted)sulfamoyl]phenyl}carbamothioyl)benzamide (1a-g) and 4-fluoro-N-({4-[N'-(substituted)sulfamoyl]phenyl}carbamothioyl)benzamide (2a-g) were synthesized as potent and selective human carbonic anhydrase (hCA) I and hCA II candidate inhibitors. The aryl part was changed to sulfacetamide, sulfaguanidine, sulfanilamide, sulfathiazole, sulfadiazine, sulfamerazine, and sulfametazine. The Ki values of compounds 1a-g were in the range of 20.73 ± 4.32 to 59.55 ± 13.07 nM (hCA I) and 5.69 ± 0.43 to 44.81 ± 1.08 nM (hCA II), whereas the Ki values of compounds 2a-g were in the range of 13.98 ± 2.57 to 75.74 ± 13.51 nM (hCA I) and 8.15 ± 1.5 to 49.86 ± 6.18 nM (hCA II). Comparing the Ki values of the final compounds and acetazolamide, compound 1c with the sulfanilamide moiety (Ki = 5.69 ± 0.43 nM, 8.8 times) and 2f with the sulfamerazine moiety (Ki = 8.15 ± 1.5 nM, 6.2 times) demonstrated promising and selective inhibitory effects against the hCA II isoenzyme, the main target protein in glaucoma. Furthermore, compounds 1d (Ki = 20.73 ± 4.32, 4 times) and 2d (Ki = 13.98 ± 2.57, 5.9 times), which have the sulfathiazole moiety, were found as potent hCA I inhibitors. Compounds 1c and 2f can be considered as the lead compounds determined in the present study, which can be investigated further to alleviate glaucoma symptoms.

Abstract
BACKGROUND In this study, new azafluorenones, 4-(4-fluorophenyl)-2-(4-substitutedphenyl)-5Hindeno[ 1,2-b] pyridin-5-one, I1-I8 were synthesized and chemical structures were elucidated by spectral analysis. All compounds were reported for the first time here. METHOD Compounds were tested in terms of cytotoxicity. They were found as cytotoxins/anticancer compounds. RESULTS It was found that the lead compounds of the series were I5 and I8 according to SI, TS, PSE calculations. When PSE values were considered, compound I5 having chlorine had the highest PSE value of 126.4. Second highest PSE value of 50.5 belonged to I8, which had thiophene ring in its chemical structure. I8 as a representative compound of the series was forwarded to cell cycle analysis. I8 arrested S phase of the cell cycle and lead to apoptosis by inducing PARP cleavage suggesting that at least one of the mechanisms of cytotoxic action of the series was apoptosis. CONCLUSION It was clearly demonstrated that compound I8 can induce early apoptosis at a concentration of 5 µM. The compounds I5 and I8 can be considered as lead compounds of the series with the highest SI, TS, PSE values for further studies.

Abstract
New mono Mannich bases, (2-(4-hydroxy-3-((4-substituephenylpiperazin-1-yl)methyl)benzylidene)-2,3-dihydro-1H-inden-1-one), were prepared to evaluate their cytotoxic/anticancer properties and also their inhibitory effects on human carbonic anhydrase I and II isoenzymes (hCA I and II). Amine part was changed as [N-phenylpiperazine (1), N-benzylpiperazine (2), 1-(2-fluorophenyl)piperazine (3), 1-(4-fluorophenyl)piperazine (4), 1-(2-methoxyphenyl)piperazine (5)]. The structure of the synthesized compounds was characterized by 1H NMR, 13C NMR and HRMS spectra. Cytotoxicity results of the series pointed out that the compound 4 had the highest tumor selectivity value (TS: 59.4) possibly by inducing necrotic cell death in series. Additionally, all compounds synthesized showed a good inhibition profile towards hCA I and II isoenzymes with the Ki values between 29.6 and 58.4 nM and 38.1-69.7 nM, respectively. These values were lower than the reference compound AZA. However, it seems that the compounds 4 and 2 can be considered as lead compounds of CA studies with the lowest Ki values in series for further designs.

Abstract
A series of new 4-(3-(4-substitutedphenyl)-3a,4-dihydro-3H-indeno[1,2-c]pyrazol-2-yl) benzenesulfonamides (7-12) was synthesized starting from 2-(4-substitutedbenzylidene)-2,3-dihydro-1H-inden-1-one (1-6) and 4-hydrazinobenzenesulfonamide. The substituted benzaldehydes from which the key intermediate was prepared by introducing 2- or 4-substituents such as fluorine, hydroxy, methoxy, or the 3,4,5-trimethoxy moieties. The compounds were tested for their cytotoxicity, tumor-specificity and potential as carbonic anhydrase (CA, EC 4.2.1.1) inhibitors. The 3,4,5-trimethoxy and the 4-hydroxy derivatives showed interesting cytotoxic activities, which may be crucial for further anti-tumor activity studies, whereas some of these sulfonamides strongly inhibited both human (h) cytosolic isoforms hCA I and II.

Abstract
Chalcones and Mannich bases are a group of compounds known for their cytotoxicities. In this study restricted chalcone analogue, compound 2-(4-hydroxybenzylidene)-2,3-dihydroinden-1-one MT1, was used as a starting compound to synthesize new mono Mannich bases since Mannich bases may induce more cytotoxicity than chalcone analogue that they are derived from by producing additional alkylating center for cellular thiols. In this study, cyclic and acyclic amines were used to synthesize Mannich bases. All compounds were tested against Ca9-22 (gingival carcinoma), HSC-2, HSC-3 and HSC-4 (oral squamous cell carcinoma) as tumour cell lines and HGF (gingival fibroblasts), HPC (pulp cells) and HPLF (periodontal ligament fibroblasts) human normal oral cells as non tumour cell lines. Cytotoxicity, selectivity index (SI) values and potency selectivity expression (PSE) values expressed as a percentage were determined for the compounds. According to data obtained, the compound MT8 with the highest PSE value bearing N-methylpiperazine moiety seems to be a good candidate to develop new cytotoxic compounds and is suited for further investigation.

Abstract
In this study, we aimed to determine the radiation parameters of some potential bioactive compounds. 1-Aryl-3-dibenzylamino-propane-1-on hydrochloride type Mannich bases were synthesized via classical conventional heating method. Aryl part was changed as phenyl (C6H5), 4-methylphenyl (4-CH3C6H4), 4-fluorophenyl ( 4-FC6H4), 4-nitrophenyl (4-NO2C6H4), 4-chlorophenyl (4-ClC6H4), 4-bromophenyl (4-BrC6H4), and 2-thienyl (C4H3S-2-yl). Mass attenuation coefficient (μm), effective atomic number (Z(eff)) and effective electron density (N(el)) of compounds were determined experimentally and theoretically for at 8.040, 8.910, 13.40, 14.96, 17.48, 19.61, 22.16, 24.94, 32.19, 36.38, 44.48, 50.38 and 59.54 keV photon energies by using an HPGe detector with a resolution of 182 eV at 5.9 keV. Radiation parameters of these compounds which can be anti-cancer drug candidate were given in the tables. The results show that phenyl ring behave like thiophene ring in terms of radiation absorption. It is thought that the results of study may drive allow the development of drug candidate new compounds in medical oncology.
